Abstract: A defined and delaminated kaolin composition exhibiting high opacity is produced by defining and delaminating a base kaolin clay so as to reduce its colloidal content. The defined and delaminated kaolin composition may also be treated with hexamethylenediamine and aluminum sulfate to further enhance opacity. Whether treated or untreated, the defined and delaminated kaolin composition functions superiorly in paper coating formulations, alone or blended with known coating clays, improving the opacity, print gloss, sheet gloss and printability of paper sheet coated therewith.

Abstract: A non-impact dot printer such as an LED printer, records grey levels of each dot by pulse width modulating the exposure on-time for each LED. The on-time of each LED for each exposure is controlled by comparing a count, representing an exposure time with a time changing output of two counters. The improved printer and method of printing employs two counters that are counting at slightly different clock rates (or at the same rates but the counts change at slightly different times). A multiplexer associated with the comparator selects which counters output is to be compared with the comparator. A particular LED may be selectively illuminated for a picture element time period determined either solely by one or the other of the counters, or by the count of one counter and the count of the other. Because of the small difference between the clock rates used to change the outputs of the counter, uniformity control of the LED's can be significantly improved by allowing fine control of LED on time.

Abstract: A fault tolerant computer system which operates to automatically provide fault tolerant operation in a manner which reduces the frequency of checkpointing, while requiring neither simultaneity nor atomicity with respect to information transmitted to backups. These advantage are accomplished by providing operation such that message transmissions from primary tasks running on a data processor to external backups may be delayed until an action is performed which will persist after failure of the data processor. Although such operation may result in the backups hot having received all of the messages transmitted to their respective primary tasks when failure occurs, recovery is nevertheless obtained using the backups, since transmission to backups is controlled so that all backups agree on the state of the data processor at the time of failure, which need not be the actual state of the data processor at the time of failure.
